Does drinking a cold glass of water send a sharp pain through your teeth? Do you wince when brushing or flossing? Tooth sensitivity is a common issue, but it's important to understand what's causing it. While there are many reasons for sensitive teeth, it can sometimes be a warning sign of something more serious, like gum disease. What Causes Tooth Sensitivity? Before we dive into the connection with gum disease, let's look at some of the general reasons why teeth become sensitive. The outer layer of your teeth, called enamel, protects the inner, more sensitive layer called dentin. When enamel wears down or recedes, the dentin becomes exposed. Dentin contains tiny tubules that lead directly to the nerve of the tooth. When these tubules are exposed to hot, cold, sweet, or acidic substances, they can trigger pain signals to the nerve, resulting in sensitivity. Common causes of enamel wear and dentin exposure include: The Link Between Tooth Sensitivity and Gum Disease Gum disease, also known as periodontal disease, is an infection of the gums and bone that support your teeth. It starts with gingivitis, an inflammation of the gums. If gingivitis is left untreated, it can progress to periodontitis, a more severe form of gum disease that can lead to tooth loss. So, where does tooth sensitivity come in? As gum disease progresses, the gums begin to recede, pulling away from the teeth. This recession exposes the roots of the teeth, which are not protected by enamel. The root surface contains dentin tubules, just like the crown of the tooth. When the roots are exposed, they become highly sensitive to temperature changes and other stimuli. Therefore, tooth sensitivity, especially sensitivity near the gum line, can be an early indicator of gum recession caused by gum disease. Other Signs of Gum Disease While tooth sensitivity can be a sign, it's important to be aware of other symptoms of gum disease: What To Do If You Have Sensitive Teeth If you're experiencing tooth sensitivity, it's important to see your dentist. They can determine the cause of your sensitivity and recommend the appropriate treatment. If gum disease is the culprit, early intervention is key to preventing further damage. Treatment for gum disease can range from improved oral care habits and professional cleanings to more advanced procedures. In some instances, restoration dentistry may be needed to address the damage caused by gum disease. Preventing Tooth Sensitivity and Gum Disease The best way to prevent tooth sensitivity and gum disease is to practice good oral care habits: Taking care of your teeth and gums is an investment in your overall health. Don't ignore tooth sensitivity – it could be a sign of something that needs attention. Early detection and treatment can help you maintain a healthy smile for years to come....
